Tattletwat 

Stealing success by being a corporate rat and being a two faced sneaky twat, is only showing bad character, untrustworthiness and a lack of compassion. That is in my opinion is grimy and scandalous.

Look there goes tattletwat again, trying to steal the bosses job.

Tattletail 

A creepy Furby-like toy from the horror game of the same name. Tattletail comes in either purple, yellow or blue fur, and it not only is this little bastard creepy, you constantly have to keep feeding, grooming, and recharging it, otherwise it will go on a complaining fit (or demonic possession fit as far as the recharging is concerned) that could very well get you caught by it's murderous mother.

For an awesome playthrough of the game Tattletail, look up the one done by YouTuber Markiplier

You know, I think I'd actually prefer a Furby over a Tattletail.......

Tattletale 

A tattle-tale is a (sort of) righteous person who complains about you every time he catches you doing something you shouldn't do. They are all very annoying.

One day, a tattletale called melvin sneedly caught bob the bully putting a stinkbomb in the teacher's desk to prank him.
He ran to the teacher's office to tell on him. Don't be such a tattletale! screeched bob. Or prepare your a**s later!! Of course he got worse punishment for using a vulagarity. Arrrghh!! Thought bob as he got caned by the teacher. I'm going to get melvin later and punch the daylights out of him! But that's another story.
The end.

Photoshop Tattletale 

A person that feels the need to point out that Photoshop was used on an image, no matter how super cool or hilarious the results may be. The fact that people ALREADY KNOW that the image is OBVIOUSLY Photoshopped does not discourage them one bit. They think this makes them seem smart or computer savvy.

"Dude, no way is that rooster THAT big, it's Photoshopped...!" "No REALLY, seven foot roosters aren't real...? I had NO idea, quit being such a Photoshop Tattletale, you're spoiling our fun..."
